Two nucleons are at a separation of one Fermi. Protons have a charge of +1.6 10⁻¹⁹ C . The net nuclear force between them is F₁ , if both are neutrons, F₂ if both are protons and F₃ if one is proton and the other is neutron. Then,

Options

  1. AF₁=F₂>F₃
  2. BF₁=F₂=F₃
  3. CF₁ < F₂ < F₃
  4. DF₁>F₂>F₃

Correct answer

B. F₁=F₂=F₃

Step-by-step solution

Since, nuclear force is independent of charge of the nucleons. Thus, nuclear force is same for any pair of two nucleons which are at same distance apart. Therefore, F₁=F₂=F₃
